    “What do you mean? Who’s your sensei then?” Mikey asks.

    “Master Leonardo!”

    “Who?” Raph asks, bewildered.

    “We don’t know anyone by that name.” Donnie adds with a raised brow, everyone nodding in agreement.

    Casey blinks at them, utterly baffled.

    “But Master Leonardo… is your brother.”

    A pause.

    Summary

    (Set in the Teenage Mutant Ninja Turtles: Mutants Unleashed)

    Basically just the Mikey going feral scene but VERY revamped and angsty.

    Did I do a ton of research on turtle instincts? yes. Did I ignore all of it for angst and plot? also yes.

    Summary

    Mikey’s smile used to light up the room. Now it barely flickers.
    Nightmares, scalding showers, flinches — his brothers know something’s wrong, but not how deep it runs.

    When the truth surfaces — what Bradford did, how he broke him — their world fractures. His family wants revenge. Mikey just wants to feel whole again.

    And maybe, with Leatherhead’s quiet patience and gentle hands, he’ll finally believe he’s not broken after all.

    Summary

    A disparaging thought came to Leo's mind, and in his rough krang-infected voice he told April: "I keep *whimper* coming undone. I should..." a few turtley clicks of distress sounded in his throat, "...go home and never show my face."

    A regretful whine escaped his mouth as he gazed at all April's broken stuff strewn across the floor.

    "Hey."

    The firm tone to his older sister's overall kind voice caught Leo's attention, so that he dared to raise his face and put his one krang and one turtle eye on her.

    She looked into both - no fear or disgust or any other negative feeling about his current state showing through. The only thing Leo could see in her eyes was the love radiating for the brother April thought she lost forever, and he couldn't help but let the corners of his mouth go up in a tiny smile when she smiled at him.

    Then she reassured her krangy mutant brother with the words:
    "If coming undone is what has to happen for me to get my brother back, then we'll have to make it alright to come undone."

    Summary

    In which self-destruction is halted by the fact that sometimes, all you need is that your friends burst into flames to save you. Which has happened more than once in Izuku's life, so it really shouldn't be that surprising.

    (Or: hey, look! This one ISN'T a USJ fic, unlike the one that has a title that relates to fire! wow! crazy world! MUSCULAR FIGHT UPON YE.)

    Summary

    April O'Neil already had to deal with all the mystic shenanigans, now she'd just like to go home. But now she has new allies and enemies to deal with, and her brain might explode if this place keeps being so different.
    -
    The four mutant brothers were still recovering from trauma and did not have time for more shenanigans after all the goddamn bullshit, it was just starting to quiet down. So why are these people here insisting they're the turtles' friends! Will they be in the future?
    -
    Turns out avoiding an apocalypse causes some separation anxiety, so when your older sister (basically) goes missing you panic, right? Well join this very lost found family for the "Rescue April" mission!

    Alright, team. New group chat. 🎉
    Because SOMEONE (glares at Mikey and Leo virtually) kept clogging up the old one with GIF wars. 🙄

    Neon_Leon💅:
    Uh, excuse me, April.
    First off, they were strategic morale-boosting visual aids.
    Second, my reaction time on that "dog with sunglasses" meme was legendary, tyvm.

    Summary

    As much as Donnie would like to be a robot and simply keep working and advancing, they were cursed with a human body. A human body with emotional and physical needs. Suddenly, their mode dropped, along with their productivity, and Donnie came to the horrifying conclusion that they were lonely. They missed Mikey’s home cooked meals, now sometimes going far too long without eating. They missed Raph’s enthusiasm and spending time with him. They were even loath to admit they missed Leo’s dumb jokes. And staying up late with Leo when neither could sleep. And ranting to Leo about their day. And listening to Leo’s absurd Jupiter Jim theories. And Leo nagging them about wearing their back brace.

    God, Donnie missed their twin.

     

    (Or: Donnie suddenly starts struggling emotionally and physically while in college, but it's a good thing Tim likes to insert himself in other people's business! If only he could help with the random seizures and memory gaps Donnie has been having. A story about college, family, surgery recovery, gay idiots, and Donnie being bad at self care.)

    Summary

    Being student director your senior year of high school is one thing, but it's even more complicated when your mom is an alien with two young daughters that she doesn't enjoy telling about her old home or the complications that come with it. (Y/n) would love to believe that she's got the hang of life in a post-shredder world, but fate seems to have other plans when the people around her start randomly breaking into song. The curse seems to follow her everywhere (work, school, the lair. Hell, even her own bedroom). She just wants a break.

    Leo's best friend being followed around by sonatas and rhapsodies is really preventing him from finally telling her how he feels. Okay, maybe he was struggling with that already, but he'd really appreciate it if it didn't start happening when he was finally gaining the courage to. Hopefully, he can use it to his advantage or something...

    Summary

    After a mishap in Witch town surrounding Donnie's connection to it, Leo pays the price and is cursed.
    At first he seems to be fine, no visible injuries or any signs of a curse actually being there. However, after a few days he falls ill, and it just gets worse from there...
    Turns out he was hit with a "life draining curse". The spell is meant to slowly drain the life out of its victims until their body is unable to support itself any longer.
    Will Donnie and the rest of the family be able to find a cure.
    Or is Leo's last breath, approaching faster then any cure can prevent?
